Since October 2021 the Institute for Solar Technology SPF is working in an international team for the EU-funded project SophiA. The focus is on sustainable, off-grid supply solutions for healthcare facilities in Africa.
Solar-based systems will be used to provide electricity, heating, cooling and clean water in container modules for remote regions.
The SolResHC project addresses research questions related to IEA PVPS Task 16 regarding "Solar Resource for High Penetration and Large Scale Applications".
Specifically, impacts of different weather scenarios on solar heating and cooling are assessed. Simulations for various future scenarios are carried out to determine the impact of weather data on the energy efficiency of different systems providing heating, cooling, domestic hot water and partly electricity for a multi-family house.
Furthermore, the influence of large feed-in from PV and other renewable energies to the electricity grid in Switzerland is analysed with a particular focus on the electricity price.
Limiting the electrical purchase and feed-in power of buildings to a low level is attractive for grid stability. Because of this limitation, the building's own solar power consumption would be optimised, the PV system output limited, peak demand reduced and, if necessary, an electric energy storage installed. Due to the different interests of the stakeholders, the advantages and disadvantages of the new technical concepts for the power limitation must be examined. The feasibility of such a concept will be investigated by means of simulations.
